Service Area

Pierce County

Pierce County is home base for Diligence Security. With our headquarters in Puyallup, our fastest response times and deepest local knowledge are right here.

From the Port of Tacoma's tideflats to the retail growth of South Hill, Pierce County spans maritime industry, logistics, healthcare, and fast-expanding suburbs. Because we're headquartered locally, our Supervisors know these communities firsthand — and can reach most sites quickly, day or night.

Local roots, professional standards

Every Officer we field is trained well beyond the state minimum, with a focus on De-escalation and documented, verifiable work. Whether you need Mobile Patrols, On-site Officers, or emergency Fire Watch, you get the same disciplined standard.

Fastest Response in Our Home County

Headquarters matters most when something goes wrong at 0200. Because our operations base and the majority of our Officers live in Pierce County, relief coverage, emergency call-outs, and same-day Fire Watch requests are filled here faster than anywhere else we work. A Supervisor can be physically on your property to verify a post, meet a Fire Marshal, or handle an escalation rather than managing it by phone from another county — and for shutdowns, sprinkler impairments, and hot-work reflash coverage, deployment inside the hour is routine.

From the Tideflats to the Foothills

Pierce County covers an unusually wide range of property in a short drive. The Tideflats and the Fife and Sumner freight corridors need perimeter patrols, gate control, and trailer and seal verification. Downtown Tacoma, the hospital district, and the Ruston Way waterfront need Officers who can hold a professional tone in front of patients, diners, and the public. South Hill, Puyallup, Bonney Lake, and Graham bring retail centers, construction sites, and residential communities where visible deterrence and documented reporting solve most of the problem before it becomes an incident. Each of those environments gets a post plan written for it, and Officers briefed specifically on the property rather than handed a generic set of orders.
